Figure 3 Findings on computed tomography. A: Computed tomography (CT) enteroclysis with negative oral contrast showing mural thickening of ileum with skip areas and sparing of cecum in a patient with Crohn's disease (CD); B: Contrast-enhanced CT scan (CECT) showing asymmetrical mural thickening in ileal loop with deep ulcerations. Note fibro-fatty proliferation of mesentery; C: CECT in another patient with CD showing mesenteric vascular engorgement (Comb sign) with fibro-fatty proliferation of the mesentery; D: CT enteroclysis with negative oral contrast showing contiguous mural thickening of the terminal ileum and cecum in a patient with tuberculosis (TB); E: CECT in a patient with TB showing mural thickening of the terminal ileum and cecum (thick arrow) with multiple enlarged mesenteric lymph nodes showing central hypoattenuating and peripherally enhancing rims (thin arrow).
